Source code, Visual Studio project, header files and relevant libraries: leptonica-1.68.

It supports the file formats, including JPEG, PNG, TIFF, and GIF. Liblept(Leptonica), written in C, is an open source library for image processing. Let’s take a further look at what Leptonica is. A simple, Pillow-friendly, Python wrapper around tesseract-ocr API using Cython - 2.5.2 - a Python package on PyPI - Libraries.io tesserocr A simple, Pillow-friendly, wrapper around the tesseract-ocr API for Optical Character Recognition (OCR). Libtiff is no longer required as a direct dependency. If you read the README file, please notice the paragraph: Dependencies and Licenses The outputs of DEBUG and RELEASE are respectively libtesseract302d.dll and libtesseract302.dll. Here are all relevant libraries that needed to be linked when building the OCR library.

Windows installer of tesseract-ocr 3.02.02.įollow the installation steps and check the option Tesseract development files:Īfter finishing the installation, find the Visual Studio project folder:.

I’ve tried different ways to set up the building environment, and finally concluded that the most convenient way is to use the installer. Tesseract is an OCR engine with support for unicode and the ability to recognize more than 100 languages out of the box.
